Paper Abstract

High repetition rate operation technology and spectral narrowing technology with compact excimer lasers whose cross-sectional dimensions are around 120 by 120 mm. High repetition rate operation over 1.5 kHz and spectral narrowing to 1 pm are reported. These technologies are essential to promising applications of ArF excimer lasers. High resolution pattern of 0.16 micrometer line and space is demonstrated by an optical laser lithography with the compact ArF excimer laser. The smallest ArF excimer laser specific to the photo-chemical surgery of cornea is also presented.
